Terra Dos T4Enter into a new dimension.

The unique HOLMER EasyLift system guarantees best harvesting results, the likeable lightweight construction stands for unrivaled soil protection, the new chassis concept with an integrated slope sensor ensures stability in all situations and the intelligent HOLMER EcoPower combines best performance with the lowest fuel consumption – they make it unrivaled.

HOLMER has perfected the defoliating cutting technique with the DynaCut. Its new geometry allows the DynaCut to harvest the entire beet without any leaves left attached. The stems remain after the topping process, which ensures height control without any losses from too-deep scalping.

More agile handling of the scalpers due to reduced weight, which prevents unscalped beets

HOLMER lifter unit Simply harvest more.

Opitmal harvesting results for 6 to 12 rows: The automatic depth control system HOLMER EasyLift makes the HOLMER lifter units unique, the driver is harvesting, what is grown, with a reduced fuel consumption. High quality materials guarantee a minimal wear and the HOLMER EasyConnect offers a maximum safty and a perfect driver comfort with 9 or 12- row lifter units.

The new HOLMER HR lifter unit, which has been given the DLG award, offers automatic and independent depth control for each individual row, optimum lifting over the entire working width, reduced wear and fuel consumption. The recipe for success of the HR-lifter unit is its modular structure of the single row unit , which is automatically adjusting to every plant population.

The HR lifter is available in three variants:

HR 45 – consistent 45 cm row spacing

HR 50 – consistent 50 cm row spacing

VHR – variable row spacing (45; 47.5; 48; 50 cm)

Its special benefits:

Avoids breakage losses through individual and automatic setting of the lifting depth for each row

Reduces unnecessary working depth and protects the machine against unnecessary wear

Lifting depth can be adjusted at the edge of the field or in machine tracks

Lower power requirement thanks to integrated vibrating share operation in every row

Integrated hydraulic, maintenance-free stone guard for each row

Forged steel share retaining components

Various possible share positions

Significantly lower tensile force required due to the new arrangement of the share body

Various lifter roller diameters for the 2nd and 4th lifter roller, in order to avoid loss in special conditions and with small beet

CleaningA tidy business.

Clean, undamaged beet = more money! The Terra Dos T4 provides the perfect basis for this. All of the cleaning and transport units, such as the transfer web, turbines and elevator are optimally adjusted for enormous flow rates. Together with the new portal axle, the flow rate on the transfer web has been increased by 40 %.

Incremental adjustments in transfer-web speed, turbine speed and elevator height can be made from the driver’s seat

Equipped according to customer specifications: the 900-mm-wide transfer web can be divided (50, 60, 70 mm), as well as the segment grates in the turbines (spring tines or sliding grates) for varying harvesting conditions

Transfer webs and turbines with independent drives are pressure-monitored and speed-regulated

Cleaning shaft between the slat conveyor and the discharge elevator for additional cleaning

With the automatically controlled, switchable holding-tank scroll, the Terra Dos T4 makes for optimum distribution of the beet throughout the holding tank. In the Terra Dos T4-40, a free-ranging claw coupling in the tank auger protects the beet and reduces damage. Optimal weight distribution across all of the axles is constantly ensured using sensors in the holding tank, the hydraulic system, the chassis and the hillside compensator system. The extended discharge elevator allows beets to be unloaded to a trailer while driving, or wide heaps to be created easily. Automatic in-line transverse and longitudinal, allow the tank to be emptied in less than 50 seconds.

FramesA solid foundation.

The Terra Dos T4 frame concept:

Portal axle with a suspended support system on the front allows for maximum tyre size (IF 800/700 R38) and creates 40% higher transfer-web throughput

Optimum stability on inclines and track-keeping on lateral slopes thanks to the low centre of gravity

Extremely good stability even in difficult turning maneuvers on the slope thanks to the low center of gravity and the optimum location of the articulation frame

Maximum maneuverability thanks to the articulation being located very close to the front axle

Extras featured by Terra Dos T4-40:

Rigidly installed middle axle provides a high basic stability of the machine (1050/50 R32) in all situations

In particular, the third axle (1050/50 R32) controlled via the central tube with a ball coupling, and supported by hydraulic cylinders with a position-sensor system and a piston accumulator, allows for:

axle-load regulation based on the holding tank fill level to ensure even loads on all axles

high level of spring comfort

greatest possible traction thanks to longitudinal compensation, lateral oscillation and axle load control as well as intelligent distribution of the driving power

suspended support system for the entire machine

lightweight, robust construction

DriveEfficient and dynamic.

In the Terra Dos T4, the latest engine technology for economical consumption comes into play. Perfect coordination with the entire drive system technology is guaranteed for all of the operating points.

Load-dependent automotive speed regulation of the engine between 1,150 and 1,550 rpm for consumption-optimized operation

Load-sensing hydraulic system for economical supply of all work, drive and steering hydraulics

Pumpdrive with integrated driveline disconnection for a reduced fuel consumption on the road

Fulfils the latest exhaust-gas standard, EuroMot 4

HOLMER EcoPowerIntelligent. Economically efficient.

EcoPower developed by HOLMER is unique in the area of selfdriving work machines. Depending on the current driving mode (harvesting or transfer) and the degree of utilization of the travel drive, on all assembly drive systems and on the central multipump drive, the HOLMER EcoPower selects the optimum range within the diesel engine and drive system map. Thus, it always ensures optimum performance while keeping fuel consumption

to a minimum.

Optimum operating point on the diesel engine, considerable increase in efficiency of all assembly drive systems and the travel drive, independently of the working process

Increased efficiency thanks to an increased number of pumps and consequently optimum coordination between pump and assembly

Overall optimization of energy management

Individual drive units which are not used temporarily are uncoupled to reduce fuel consumption

WorkplaceFunctionality with the highest level of comfort.

The short harvesting season means long working hours. Achieving the best working results requires a high level of comfort for operating personnel. This is guaranteed by the HOLMER SmartDrive – an operating concept perfectly geared to assist the driver. The new all-glass, sound-insulated HOLMER comfort cab II, with its low-reaching, single front glass pane, provides an optimal view of the scalpers, lifting shares and cleaning rollers. The sides of the machine, including the discharge elevator, can also easily be viewed with a glance over your shoulder.

TerraDAT is a software program developed by HOLMER for convenient management of job data, customer and machine data on a PC. In particular, it allows users to:

Create databases for customer data, and transfer them to the machine using a USB stick

Analyse all of the machine, driver and harvest data, operating overviews and individual assignment

Monitor and send reminders about maintenance

Track current lifting data online, together with the GSM module (optional)

SteeringTrail-blazing technology.

The Terra Dos T4 is steered automatically during the lifting

process – via the leaf sensor and the share bodies, which

directly affect the rear axles and the front axle. The leaf topper and lifting unit adjust to the ground conditions independently from the vehicle. Thus the lifter also works very precisely even on extremely difficult, uneven ground, with minimal losses. The driver receives assistance, and is able to concentrate fully on the actual tasks, taking advantage of the yield-related parameters.

Pivoting range of the articulation of over 60° for maximum maneuverability

Extremely small (inside) turning circle of 6.50 m for the fastest turning times, even on confined headlands

Automatic axle support and a low center of gravity of the vehicle guarantee outstanding slope stability even on very uneven ground

The independently driven front axle allows automatic and manual adjustments to the preprogrammed response for the rear axles, for optimal traction in every position (from positive through zero down to negative)

Reduced wear and waste along with maximum driving stability thanks to the ideal lead

The central or left-hand/right-hand offset position of the axles provides lifting flexibility. The following steering variants can be activated via the ergonomic joystick at the push of a button:

Road travel: speeds of up to 40 km/h infinitely variable; the steering wheel only controls the front axle (up to 13 km/h, includes articulated steering)

Four-wheel steer: the front and rear axles are operated via the steering wheel

Combi steer (combination of turn steer and diagonal steer): the full articulation angle is also available in diagonal steer mode to ensure optimum preservation of the soil while driving to the beet heap or towards the next track
